Feat: Improve 'user_canvan_version' delete and 'document' delete performance (#6553)

### What problem does this PR solve?

1.  Add delete_by_ids method
2. Add get_doc_ids_by_doc_names
3. Improve user_canvan_version's logic (avoid O(n) db IO)
4. Improve document delete logic (avoid O(n) db IO)

### Type of change

- [x] Performance Improvement
